Objective. The aim of the present study was to evaluate the predictive ability of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), waist-to-height ratio (WHtR) and body fat percentages (BF%) for the presence of metabolic syndrome (MS). Methods. Through a random sampling probabilistict were selected 1934 adults ≥30 years with some cardiovascular risk factor. Trained personnel obtained anthropometric measures (weight, height and WC) and a fasting blood sample was collected to determine lipids profile and glucose levels. We evaluated the association between BMI (weight/height2), WC and BSI (WC/( BMI2/3x height1/2), and glucose, triglycerides, total cholesterol, HDL-Cholesterol and systolic and diastolic blood pressure. The indicators was divided in to quartiles (Q) and we computed a lineal regression models to compare the mean of MS components in different quartiles, adjusting for sex and age. Results. The mean BMI was 28.3 kg/m2 (women 28.8 kg/m2 and men 27.0 kg/m2), WC was 94.8cm (94.9 cm women and 94.3 cm men); and BSI was 0.083 (0.083 women and 0.082 men). Compared quartile 4 (Q4) versus quartile 1 (Q1) of BMI and WC, we found statistically significant difference of triglycerides (BMI:42.2 mg/dl; WC: 43.8 mg/dl) , HDL-Cholesterol (BMI: -4.7 mg/dl; WC: -5.1 mg/dl), systolic blood pressure (BMI: 7.4 mmHg; WC: 7.5mmHg) and diastolic blood pressure (BMI: 8.4mmHg; WC: 7.8mmHg). For BSI there were no significant difference for this components but it was difference for glucose levels (14.1 mg/dl). Conclusions. BMI and WC shows to be good indicator for risk of lipids and blood pressure but not for glucose, while BSI are more sensible for glucose but not for the other risk factor evaluated. Because this is a cross sectional study, the results are not conclusive. It is necessary more analysis to compare the sensibility and specificity of this indicators given some cardiovascular results.
